Abstract
Lead, is the most common toxic metal that causing damage to the environment and human health due to its accumulation and persistence in the environment. The possibility of using biosorption unmodified rice straw (RS) was studied to eliminate lead ions from synthetic industrial wastewater.  The impact of the initial concentration for lead (5–200 mg/l) and the contact time (10–120 min) were studied at 25°C and pH 5 of stirring solutions. Different analytical techniques such as Scanning Electron Microscope (SEM), Energy dispersive X-ray (EDX), and Fourier-transform infrared spectroscopy (FTIR) were used to figure out the change of rice straw adsorption capacity Moreover, The kinetic models pseudo-first and second- order and both of Freundlich and Langmuir isotherm models have been tested. The results obtained show a significant removal of the lead content by approximately 94 % using unmodified rice straw (RS). Adsorption data was fitted with Freundlich isotherm model and pseudo - second order kinetics for unmodified rice straw
